When this check box is clear, the Walk tool disregards the world up vector,
and the camera is walked with its current up orientation unaffected.
Use Viewpoint Linear Speed When this check box is selected, the Walk tool
will respect the Viewpoint Linear Speed setting. In this case, the Walk speed
slider will act like a multiplier.
When this check box is clear, the Walk tool will work independently of the
Viewpoint Linear Speed setting, using a fixed value set with the slider.
Walk Speed Sets the speed of the Walk tool from 0.1 (very slow) to 10 (very
fast).
Zoom Tool
Enable Single-Click Incremental Zoom In When this check box is selected,
single clicking over the Zoom wedge increases the magnification of the model.
When this check box is clear, nothing happens when you single click over
the Zoom wedge.
Orbit Tool
Keep Scene Upright When this check box is selected, the Orbit tool behaves
similarly to the classic Orbit mode, with orbiting constrained along the XY
axis and in the Z direction.
When this check box is clear, the Orbit tool behaves similarly to the classic
Examine mode, and you can roll the model around the pivot point.
Center Pivot on Selection When this check box is selected, the objects
selected before the Orbit tool are used to calculate the pivot point to use for
orbiting. The pivot point is calculated based on the center of the extents of
the selected objects.
